Taidacent 12V Soil Humidity Control Automatic Plant Irrigation System Garden Watering Moisture Sensor Switch Soil Moisture Relay Module

12V two-way soil moisture relay module higher than humidity start relay automatic watering use: Adjust the soil humidity control threshold by potentiometer, connect the relay normally closed end to automatically water the garden, garden watering, control the soil moisture of the family flower pot, various electronic games, etc., with high-power relays, can control high-current equipment It is greater than the set humidity and automatically activates the relay to pull in. It is automatically disconnected less than the set humidity. product description: 1. Using the high-quality soil sensor produced by the company to test the soil moisture and widening the sensing area to improve the conductivity; 2. The product can control the humidity of the soil in a wide range, and the corresponding threshold is controlled by the potentiometer. When the humidity is higher than the set value, the relay is started to pull in. When the value is lower than the set value, the relay is disconnected; 3. When the humidity is detected to be critical, the relay will not flash and a stroboscopic phenomenon will occur; 4. The product adopts Songle high-quality relay, which can withstand 1500W load and meet the requirements of most people; 5. The product has a power indicator and a relay pull-in indication;
